What CALFRAC WELL SERVICES CORP’s FMCSA record shows

Each field from the public registration, and what it means when you’re vetting this carrier.

USDOT number 980037
The USDOT number is FMCSA's permanent ID for this company. It never changes, even when the business renames, moves, or changes owners, so it's the most reliable way to identify CALFRAC WELL SERVICES CORP.
MC number None on file
No MC number is on file. That's normal for private fleets hauling their own goods and for intrastate-only carriers, but a company with no MC number can't legally haul regulated interstate freight for hire.
Operating status Active
FMCSA lists this USDOT number as active. Active status alone doesn't confirm current insurance or operating authority; those are separate checks.
Operation type Interstate
Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
Fleet size 577 power units, 400 drivers
CALFRAC WELL SERVICES CORP self-reports 577 power units (trucks and tractors), which makes it a large fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
Last MCS-150 update Dec 23, 2025
The MCS-150 is the registration form where carriers report their address, fleet size, and operations. CALFRAC WELL SERVICES CORP last filed it on Dec 23, 2025. That's within FMCSA's two-year update requirement, so the company details here are reasonably current.
